Re: Windows - have program replace itself

Well if you are copying the new version over the old version, this should work:

exec($0);

IIRC, the problem is that Windows won't let you overwrite or delete a running program; that's why upgrades of running programs often require a reboot. Assuming `exec` works properly on Windows, one possible workaround would be to launch a second script which would download the first script, then re-execute it: `# script 1 sub upgrade { exec('upgrade',$0,@ARGV) or die "exec failed! $!\n"; } # upgrade script download_new_version($ARGV[0]); exec(@ARGV) or die "exec failed! $!\n";` [download]	[reply] [d/l] [select]
